i would like to know few lugormod cvar commands.First i want to know how to disable Security code (totally) from serverSecond i want to know how can i change, how many days will account be activethird i would like to know few other useful cvar cmds for server

you mean the shields and medpacs from SP? they don't work properly in MP, so it is best to delete them. If you use the latest lugormod version, use /entitylist remove XXXX. Replace the XXXX with item_shield_sm_instant, item_shield_lrg_instant, and item_medpak_instant.If you are using an older version, use /rcon entitylist remove XXXX.

If you still want to have pickup-healing items, use item_shield and item_medpac. Those ones are designed to work in MP. Most of the time i just use misc_model_health_power_converter and misc_shield_floor_unit.
